WATER DISTRIBUTION VALVE TOPOLOGY FOR RELIABILITY-ANALYSIS

This paper points out the importance of adequate valving in providing water distribution system reliability and the problems in assessing th e reliability of a water distribution system, using a link-node repres entation commonly found in pipe network models. The paper suggests usi ng an approach involving 'segments' of a distribution system that can be isolated with valves as the basic unit for assessing reliability, a nd illustrates the use of a graphical approach to analyze the adequacy of valving.
